First breeding evidence of Glossy Ibis Plegadis falcinellus at Lake of Grand-Lieu (West France). A pair of Glossy Ibis bred for the first time at Grand-Lieu lake (western France) in spring 2011 after previous records of this species since 1994. The pair was found in a mixed colony of African Sacred Ibis, Eurasian Spoonbill and Ardeids (Grey Heron, Cattle Egret, Little Egret, Great Egret). The eggs were laid between 9 and 17 April in the same time-period than the first clutches of Sacred Ibis and Spoonbill. The nest was built in a tree Salix atrocinerea on a floating peat bog. Four young were found on 19 May, they regurgitate Red Swamp Crawfish Procambarus clarkii, a species which largely invaded this lake in 2007
